## Homework Statement

Is the least count constant for Vernier scale like 0.1 mm or variables?

2. The attempt at a solution

2. The attempt at a solution

If the main scale readings are 10 mm and the vernier scale readings are 9 mm, the least count is MSD/VSD = 9/10 = 0.9 So the least count is 0.1 mm for every count in the vernier scale

again if MSD is 50 mm and VSD is 49 mm, the least count is MSD/VSD = 0.98 So the least count is 0.2 for every count in the vernier scale
